Can an administrator use the parameter COMPRESS_LZ1_CREATE=1 to enable LZ1 compression by default in their environment?
Development have removed the parameter COMPRESS_LZ1_CREATE from the release code
This parameter was implemented for initial testing and not designed or ever intended for general release. Development deliberately removed the parameter in 8.5.2 . There is an enhancement request SPR DPBE8TVN2F requesting that this functionality be implemented again in a future release
